Tigo Energy Expands Solar-Plus-Storage Solutions in Czech Republic with Full Certification and Installer Support
Tigo Energy, Inc. (NASDAQ: TYGO), a global leader in intelligent solar and energy software solutions, has announced a significant milestone in its European expansion strategy. The company’s full portfolio of three-phase Tigo EI Inverters has successfully passed the stringent certification process for compliance with the Czech Republic’s PPDS P4 requirements, also known as Annex 4 of the Distribution System Operation Rules. This certification is a critical step in enabling solar inverters to be connected to the national grid and confirms alignment with the technical conditions established by the European Commission and enforced by local utility companies.
The achievement marks a key step in Tigo’s broader strategy to strengthen its foothold in the European residential energy market, particularly in the Czech Republic, where demand for integrated solar-plus-storage systems continues to rise. With the rapid growth of rooftop solar installations—estimated to reach nearly 967 megawatts (MW) in 2024, primarily from residential systems—Tigo is well-positioned to support installers and homeowners with a full-stack solution that is smart, scalable, and resilient.
A Decade of Presence and Continued Trust in the Czech Market
Tigo is no newcomer to the Czech solar sector. Over the past ten years, thousands of Czech installers have adopted Tigo’s Module-Level Power Electronics (MLPE) solutions, notably the TS4 Flex MLPE, which enhances system safety and performance. In 2024 alone, installations in the country have already reached approximately 107 MW using Tigo MLPE technology, underscoring the company’s strong market presence and trusted reputation.
This solid foundation has enabled Tigo to launch its next generation of residential energy systems with confidence. Building on its established success with MLPE, the company is now offering the Tigo EI Residential Solution—an all-in-one ecosystem that unifies solar power generation, battery storage, backup power, and energy management in a seamless, user-friendly platform.
Introducing the Tigo EI Residential Solution: A Complete Energy Ecosystem
The Tigo EI Residential Solution represents a major step forward in home energy integration. Designed with modularity and simplicity in mind, the system incorporates key hardware and software components to deliver a flexible and comprehensive energy experience for homeowners and installers alike.
The core components of the solution include:
- TS4 Flex MLPE for rapid shutdown, optimization, and monitoring
- Single- and three-phase inverters for a range of grid configurations
- Modular battery storage that allows customers to scale their backup capacity
- The EI Link, a compact cabinet that houses all wiring, communication infrastructure, and backup systems in a centralized unit
Further enhancing the system are two innovative additions: the GO EV Charger, which directly integrates electric vehicle charging into the platform, and the GO Junction, a module that enables coordination between the energy system and home heat pumps. These features combine to make the Tigo EI Residential Solution a future-proof platform that supports energy independence and facilitates the electrification of home appliances and transportation.
Certified and Ready for the Grid
Achieving compliance with the Czech Republic’s PPDS P4 regulations was a top priority for Tigo as it introduced the EI Residential platform to the region. The PPDS P4 guidelines ensure that grid-connected inverters meet specific technical and safety standards to maintain grid stability and protect both utility infrastructure and end-users.
“This certification is more than just a regulatory hurdle—it’s a gateway to enabling the seamless deployment of our advanced energy systems in the Czech Republic,” said Jing Tian, Chief Growth and Revenue Officer at Tigo Energy. “Our inverter technology, now validated for grid operation in this important European market, will allow homeowners and installers to realize the full value of integrated solar-plus-storage systems backed by intelligent software.”
A Streamlined Experience for Installers
Tigo has invested significant resources into enhancing the installer experience through its Tigo Green Glove Service Program, which has gathered input from hundreds of professional engagements. These insights have informed upgrades across the board—from installation and commissioning to long-term operation and maintenance.
Key improvements to the Tigo EI Residential system include:
- Faster installation and setup with fewer manual steps
- Improved autonomy for installers with comprehensive tools, documentation, and in-app guidance
- Seamless commissioning across Tigo components, reducing errors and setup times
- Integrated software support via the Energy Intelligence (EI) platform, enabling proactive system monitoring and diagnostics
These enhancements empower solar professionals to deliver high-quality installations more efficiently, while ensuring that homeowners receive reliable and optimized performance from day one.
Miroslav Vavera, CEO of leading Czech installer SUNLUX s.r.o., praised the benefits of Tigo’s new solution:
“Tigo securing this certification for inverter operation on the grid infrastructure of the Czech Republic means that installers like us now have a reliable, all-in-one solution that is easy to install and configure, with a flexible, modular architecture that fits a wide range of residential customer needs.”
He added,
“Beyond installation, Tigo also offers proactive monitoring through the Energy Intelligence software platform, which will significantly streamline our operations and maintenance program. For homeowners, this means a system that is always ready to deliver energy security, even during outages, elevating the role of batteries from optional add-ons to essential pillars of energy independence, all easily managed through a user-friendly app.”
Driving the Energy Transition with Innovation and Integration
Tigo Energy’s EI platform addresses a crucial market need for integrated energy solutions that go beyond power generation. As energy costs fluctuate and power outages become more frequent, the need for robust, intelligent, and adaptable systems grows stronger. Tigo’s offering provides Czech homeowners with a path toward energy resilience and sustainability while giving installers a comprehensive toolkit to meet diverse customer needs.
The all-in-one nature of the EI Residential system is a response to changing consumer expectations and regulatory demands. As more European countries adopt rapid shutdown requirements and support decarbonization goals, systems that unify solar, storage, electric vehicles, and heating into a single manageable platform will likely become the standard.
Events and Training for the Czech Installer Community
To support its growing installer network, Tigo will be actively engaging with solar professionals across the Czech Republic. Installers are encouraged to:
- Attend the Iftech Solar Fvest in September 2025, an all-day hands-on event hosted by Tigo distribution partner Iftech. Attendees will experience the EI Residential system in action and interact with Tigo experts.
- Register for the Czech-language EI Residential Solution webinar for solar installers in July, which will cover product features, system design, installation tips, and live Q&A with Tigo representatives.
Czech homeowners interested in deploying a Tigo energy system can access a comprehensive list of certified Tigo installers on the company’s website. These professionals have been trained in the deployment and maintenance of the Tigo EI platform and are equipped to deliver top-tier service.
